api: Can't generate API documentation.

I’m facing the same issue [ErrorException] Missing argument 4 for Dingo\Blueprint\Blueprint::generate(), called in vendor/dingo/api/src/Console/Command/Docs.php on line 95 and defined I put empty string as a fourth parameter in $contents = $this->blueprint->generate($this->getControllers(), $this->getDocName(), $this->getVersion(), ''); at line 95 in the “handle” method inside “vendor/dingo/api/src/Console/Command/Docs.php” and it worked fine for me. it’s just a workaround and I hope it helps. thanks

I try a "dingo/api": "dev-master" but the command artisan api:docs --output-file docs.md -vvv return

Still getting this error :

Fixed it by commenting out https://github.com/phpDocumentor/ReflectionDocBlock/blob/master/src/DocBlockFactory.php#L84. Not sure the negative effects of this but it allows me to generate the docs which is what I need for now.

@hskrasek in fact that did work, forgot about stability settings mentioned by @johannesschobel Thank you for the temporary fix, hope this will get resolved soon. Cheers.

@mohamed-atef thanks! that worked as a dirty hack to at least get our documents published. Would be helpful if we get an official fix on this.

[Solution] checkout master branch "dingo/api": "dev-master",

add min stability and prefer stable option to composer.json "minimum-stability": "dev", "prefer-stable" : true
